Miniature momentary action switch
30 - 42 V, 50 mA, IP40 - IP67 SCHURTER

Miniature push button switches with a low height of 4,55 - 4,95 mm for surface mounting (SMS) and PCB
mounting (PMS).
The SMS has large flat surfaces on the top side as well as on the other sides, which are also parallel to each
other. This makes the SMS a perfect switch for automatic mounting.
The SMS switch is suitable for the SMD soldering process "IR-Reflow".
The switch comes with the SMD-leads "Gullwing and J". With J-leads the switch can be lined up with a spacing
of 1/2" in one coordinate direction, and with > 13,5 mm in the other coordinate direction. With Gullwing-leads,
the switch can be arranged with a spacing of 1/2" in one coordinate direction, and in the other coordinate
direction with > 17,5 mm.
A minimum spacing of 1/2" to 15 mm is necessary for the PCB version.
Basically, the SMS and PMS come in two basic versions concerning the degree of protection. Available are IP
40 and IP 67. According to the degree of protection the IP 40 version is not proof against fluxing and washing,
whereas the IP 67 version is. Consequently, the IP 67 version can be exposed to the specified soldering and
cleaning processes.
The miniature push button switches feature a very good tactile response with an actuation force of about 2N.
SMS and PMS are also available with an elongated actuator. These variants serve as base modules for the
SMS/PMS variable height version.
