DPDT relay with off postion?

dbc1218

Does anyone know where I can get a DPDT (double pole double throw) relay with an off position? I know you can get switches like this with a center off position but didn't know about a relay. I want to use it for a project, using a remote control car that has differential steering, to control one of the two motors. I don't even know if something like this is made but maybe one of you guys have seen it.

How about two DPST relays instead? You'd need two actuation signals anyway for a center-off relay. 'Might as well just use two regular relays.

Such DPDT C/O relays have two coils. One coil actuates the armature in one position or direction, and the other actuates it in the opposite position or direction. If neither coil is actuated, the relay self-centers for an "OFF" position.

More information can be provided, if you provide some specifications. The primary concerns here are voltage, amperage and mounting.

You could also just use 4 spst relay in an H-bridge pattern.

You guys are right with the multiple relays and you would need the same number of control signals. I think thats going to be the easiest way to go. Thanks for the help.

If you looking for RC switches. these little guys work great. We use them in RC combat robots all of the time.. They accept standard PWM signals from a receiver or you can control them with a Basic stamp2. From what you posted you probably could use the RCE 220 to control the on/off direction of a motor. You can wire it to work as an H-bridge with a couple of jumpers.
