Marquardt 1841 - above standard classics

Classic push-button switches are favorite for many decades, maybe also because they´re well known already from the beginnings of electronics. Probably, a nostalgia is not the only reason making them popular, but mainly an easy control, when even an unacquainted person knows, that it´s something “what has to be pushed” to change a status of an electric device.

Exactly a term “to change a status” is important, because at these switches it´s not possible (or not easily visible), whether it´s switched on or off. Though it´s true, that the majority of such switches is a little bit pushed down (lowered) in a switched on status, but the difference is often small. That´s why these switches are not suitable for applications, where from safety reasons it´s necessary to know tha status of the switch before connecting to a mains line.

Switch 1841.1301 (SPNC) belongs to a top in this segment and offers a really pleasant control and a quality switching system with a mechanical endurance of min. 100 000 cycles. 6A/ 250V is far sufficient for many applications and assembly is simple - by means of an M12 nut supplied. An interesting supplement is also a neoprene cap integrated with an M12 nut, enabling to gain a considerable resistance to water and dust. Also available are 2-pole versions - 1842 and also versions functioning as a push-button (momentary).

There are 2 nuts supplied. One is “regular” - hexagonal and the other one is a round type intended to be used as a top cover on a front panel. Further detailed information will provide you the Marquardt 1840 datasheet.
