Plunger switch help please?

[Petel]

Could anyone please advise as to the following?

Seeking a plunger switch ( car door sort of thing ) with a " momentary " function, to be fitted into a gate post, so that when the gate is opened a momentary signal is sent. Have been to all the usual sites and done all the usual searches, with no result.

There are plenty of NO/NC types ( and several which will do both ) but I am yet to find one with a momentary function.

If anyone knows of such a plunger switch being commercially available ( perhaps in a security system setup ) then would be most grateful to hear of it.

Many thanks, Petel

Something like "Switch, Pushbutton, DPDT, Momentary, Gold PC Terminals" RS Stock No. 2508397018 ? On the Welcome to rswww.com site. They may well have others.

You could use any trigger in conjunction with a timer similar to this to give the required pulse

Timer Module - The 0260 Adjustable Timer

Many thanks to Toolguy and Spider for the replies.

The solutions offered would indeed do the job but are not quite what I am looking for.

If anyone is aware of an " off the shelf " spring loaded, plunger switch which would provide the function mentioned, would be most grateful to hear of it.

Thank you, Petel

Does it need to be a plunger switch?

Couldn't you get away with using the outdoor mag contacts the alarm boys use, and maybe a contactor? Depending on what you exactly have in mind, I'm not too sure from your post.

Just a thought

What do you want it for?
