Keypad switches

[Zephod]

I've got an electric lock on my bus. That works with a key. Basically, a key switch turns a linear actuator on and the actuator breaks the current when it's done moving.

What I'd like to do is to put a keypad so I can get in without my key. I'll probably put the keypad underneath somewhere.

I see lots of keypads but not yet one that'll switch power on and keep it on.

Run the keypad output to a latching relay. That will take the pulse that the keypad creates to a solid on and off to feed the actuator.

Hmm... hadn't thought of that. That, of course, would unlatch as soon as the actuator cuts off the power.

No that is the object of a latching relay, it stays in the last position it was switch to; each pulse switches it from on to off and it stays there until switched again.  I used them in my bus to control light circuits. Run a many wires as you want/need from the ground of the relay to grounding switches. I have push button switches where ever I want to control a light from, hall lights can be switched from the bedroom, kitchen, living room or entry door.  I used mechanical relays but someone on the board built solid state latching relays.

Could you retrofit one of the touch pads used to control a garage door opener? We have a key switch as a backup, but the main control is done by the touch pad mounted on the jamb.

I locked myself out of my bus and got in only because I'd given my girlfriend a back door key. I need to be able to unlock the door with a digital keypad. I can hide that under the hood.

What if you hid a backup key somewhere on the chassis in a magnet case?

I'd prefer a code lock. That way it can't fall off or be found by a no good.

Hi Zep,

I have these on my two shop doors. They are weatherproof and simple to program.

I've looked at those on eBay too. My concern is that most have the electronics built into the keypad so all a bad guy has to do is to rip the keypad off and start crossing wires.

True, but at that point they can just start busting glass too.

I had a 1970 cadillac convertible at one point in my life. I didn't lock the doors on that car because I'd rather someone take the $75 radio rather than smash the $200 side glass, or cut the $900 top.

If someone wants to get in, they're going to get in. Locks are for the honest folks.

Z what do you have in that bus that's enticing to burglars? If you don't have electronics, flat screens or anything else of major value I doubt they will want in. But I agree, if they are going to go thru the hassle of ripping apart a keypad they will bus one of your bazillion windows

Fair point. I've made it look as secure as I can. I suppose in that case, a $25 Chinese keypad is probably ok.

I just ordered one of these. Hope it's easy to use.

Simple solution. Just put a sign in the window that says "NO AIR JORDAN'S ON-BOARD"
