recommended add-ons


Those parts are not part of the standard pack!

For enhanced optics (more originality) we offer an add-on (dummy) contact breaker housing and springpost to hold it. Those parts are not needed for any function and have merely optical value. They are NOT part of the standard pack, but are optional extras.
