SURAJ Micro Switches Type SM3 series (SPDT) are unsealed sensitive light weight momentary switches featuring snap action contact movement, high electrical rating and long life. These switches are precision built and small in size and shape of international design standards to meet requirements of numerous AC & DC applications where repeat accuracy is an essential need. SM3 Switches are operated by small force or movement either directly acting on the plunger or through a wide range of integral and auxiliary actuators including roller type and push buttons. |
