4p Push Button Switch

Comparison of 4P Push Button Switch and 6P Push Button Switch

6-Pin Version:

•Signal Group 1: Pin1 (COM), Pin2 (NC), Pin3 (NO)

•Signal Group 2: Pin4 (COM), Pin5 (NC), Pin6 (NO)

•(In some models, Pin2/Pin5 are mechanical mounting pins with no electrical connection)

4-Pin Version:

•Retained: Pin1 (COM), Pin3 (NO), Pin4 (COM), Pin6 (NO)

•Removed: Pin2 (NC/mounting pin), Pin5 (NC/mounting pin)

•Actual electrical connection: Only one set of SPST (Pin1-Pin3 or Pin4-Pin6)

The reason this pushbutton switch was simplified from a 6-pin (DPDT) to a 4-pin (SPST) configuration

1. Functional ReductionMost scenarios only require single-pole single-throw (SPST) switching. The additional set of contacts on the 6-pin version is redundant and can be removed without affecting core functionality.

2. Cost and Efficiency Optimization: Reducing pins lowers mold and material costs, simplifies SMT placement processes, and enables more compact PCB layouts to save manufacturing expenses.

3. Mechanical AdaptationThe eliminated pins are typically non-functional fixed pins. In applications with low mechanical strength requirements, they can be removed without compromising electrical performance.

4. Industry Compatibility: The 4-pin configuration is a universal standard, facilitating direct replacement without requiring PCB redesign.

1. Q : Do you customize material of switch as buy's requirement ?
A : Yes, we do. we customize different colors, materials, shapes etc. Please provide us your spec sheet and requirement

2.Q : Could I get a sample to test ?

A: Sure, we provide you free sample, but shipping cost should be paid by buyer

3. Q : How quick could you deliver a order ?
A: For custom order, it takes about 15 days normally. It depends on quantities of your order.
