The 49-59121 is a single-pole single-throw (SPST) momentary action Sealed Pushbutton Switch with solder terminal, round bezel and a black button. It fits a 16mm panel cut out. Held in position by a snap fit retaining mechanism, the microswitch has a maximum current rating of 10A and the advantage of SPDT-DB contacts to cover all circuit requirements. Being double break, the contacts also provide reliable switching of DC loads. The body and button are made from PBT, a hard wearing thermoplastic polyester that is suitable for surface or sublimation printing or engraving. The switch body is fitted from the front of the panel and is locked down with an M16 nut using a 20mm spanner. Panel sealing is achieved by the use of a sealing washer which is placed behind the head of the bezel. To attain the correct sealing, the nut should be tightened to a recommended torque of between 1Nm and 1.5Nm not exceeding 2Nm.
