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. 1.2 SMS/PMS Variable Height The variable height SMS/PMS consists of the SMS/PMS base module with elongated actuator and a slip-on button with eight variable heights. The PMS will be supplied with a mounted button. The button for the SMS has to be ordered separately. After soldering, the button must be put on the base module with elongated actuator. Heights between 8,5 mm and 13,75 mm for the SMS and 8,35 mm and 13,60 mm for the PMS are available. Depending on the base module being used, degree of protection for the variable height SMS/PMS is IP 40 or IP 67.
