Honeywell 11SM2440 Snap Action Switch SPDT Equivalent & Substitute Parts

Part Overview

The Honeywell 11SM2440 is an active-status snap action switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A DC at 30V. This chassis-mount component features a round pin plunger actuator with solder lug termination and is designed for on-momentary switch function applications. The part is RoHS compliant and maintains unlimited moisture sensitivity level (MSL 1) rating.

Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: SPDT circuit configuration, 5A current rating, chassis mount construction, round pin plunger actuator type, solder lug termination, and on-momentary switch function. Substitute parts from E-Switch (MS series) provide functional alternatives with differing voltage ratings and operating force specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified from the E-Switch MS0850500 series based on the following matching parameters:

Core Electrical Parameters (Required Match):

• Circuit: SPDT
• Switch Function: On-Mom
• Current Rating: 5A
• Actuator Type: Round (Pin Plunger)
• Mounting Type: Chassis Mount
• Termination Style: Solder Lug

Allowed Variation Parameters:

• Voltage Rating: Substitute parts rated 125V AC (higher than 30V DC main part)
• Operating Force: Varies across substitute options (60gf, 80gf, 250gf)
• Operating Temperature: Substitute parts rated -25°C to 85°C (narrower than main part)
• Mechanical Life: Substitute parts rated 1,000,000 cycles (lower than main part's 10,000,000 cycles)
• Electrical Life: Substitute parts rated 50,000 cycles (specified, whereas main part has no electrical life specification)

The three E-Switch substitute parts (MS0850500F060S1A, MS0850500F080S1A, MS0850500F250S1A) differ only in operating force specification, allowing selection based on application-specific actuation requirements.

Engineering Selection Recommendations

Honeywell 11SM2440 Selection Criteria:

• Primary choice for applications requiring 30V DC operation
• Suitable for extended temperature range operation (-55°C to 125°C)
• Specified for high mechanical cycle life (10,000,000 cycles)
• Active product status with established supply chain

E-Switch MS0850500F060S1A Selection Criteria:

• Applicable for 125V AC circuits requiring lowest operating force (60gf)
• ROHS3 compliant with REACH unaffected status
• Suitable for applications with light actuation requirements
• Operating temperature limited to -25°C to 85°C range

E-Switch MS0850500F080S1A Selection Criteria:

• Applicable for 125V AC circuits with moderate operating force requirement (80gf)
• ROHS3 compliant with REACH unaffected status
• Highest current inventory availability (1250 Pcs)
• Operating temperature limited to -25°C to 85°C range

E-Switch MS0850500F250S1A Selection Criteria:

• Applicable for 125V AC circuits requiring highest operating force (250gf)
• ROHS3 compliant with REACH unaffected status
• Suitable for applications with heavy actuation requirements
• Operating temperature limited to -25°C to 85°C range

All substitute parts maintain SPDT circuit configuration, 5A current rating, chassis mount construction, and solder lug termination compatibility with the main part. Selection between E-Switch variants depends on specific operating force requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can E-Switch MS0850500 series parts directly replace the Honeywell 11SM2440 in all applications?

A: E-Switch MS0850500 series parts share core electrical and mechanical parameters (SPDT circuit, 5A rating, chassis mount, solder lug termination, on-momentary function). However, substitution requires verification that the application operates within the E-Switch parts' voltage rating (125V AC versus 30V DC), operating temperature range (-25°C to 85°C versus -55°C to 125°C), and mechanical life specification (1,000,000 cycles versus 10,000,000 cycles).

Q: What is the primary difference between the three E-Switch substitute parts?

A: The three E-Switch substitute parts (MS0850500F060S1A, MS0850500F080S1A, MS0850500F250S1A) differ only in operating force specification: 60gf, 80gf, and 250gf respectively. All other electrical, mechanical, and environmental parameters are identical. Selection depends on the actuation force requirement of the specific application.

Q: Are there voltage compatibility considerations when substituting the Honeywell 11SM2440 with E-Switch parts?

A: Yes. The Honeywell 11SM2440 is rated for 30V DC operation, while E-Switch MS0850500 series parts are rated for 125V AC operation. Applications operating at 30V DC must confirm that the E-Switch parts' 125V AC rating is suitable for the circuit design. The higher voltage rating does not prevent use in lower voltage applications, but circuit compatibility must be verified.

Q: How do operating force specifications affect part selection?

A: Operating force determines the mechanical effort required to actuate the switch. The Honeywell 11SM2440 requires 141gf operating force. E-Switch alternatives provide 60gf (MS0850500F060S1A), 80gf (MS0850500F080S1A), or 250gf (MS0850500F250S1A). Applications with specific actuation force requirements must select the E-Switch variant matching those requirements.

Q: What are the mechanical life implications of substitution?

A: The Honeywell 11SM2440 specifies 10,000,000 mechanical cycles, while all E-Switch MS0850500 series parts specify 1,000,000 mechanical cycles. Applications requiring extended cycle life should retain the Honeywell part. Applications with lower cycle requirements can use E-Switch alternatives.

Q: Are all parts RoHS compliant?

A: Yes. The Honeywell 11SM2440 is RoHS compliant. All E-Switch MS0850500 series substitute parts are ROHS3 compliant. Both compliance levels are acceptable for RoHS-regulated applications.

Q: What is the operating temperature consideration for substitution?

A: The Honeywell 11SM2440 operates across -55°C to 125°C. E-Switch MS0850500 series parts operate across -25°C to 85°C. Applications requiring operation below -25°C or above 85°C must use the Honeywell part. Applications within the -25°C to 85°C range can use E-Switch alternatives.

Q: Do all parts use identical packaging?

A: Yes. The Honeywell 11SM2440 and all E-Switch MS0850500 series substitute parts use bulk packaging and solder lug termination, ensuring mechanical and electrical compatibility in assembly processes.
