Abstract
A condition settable combination gas cylinder and electric switch, the switch being mounted on the extended piston rod of the cylinder. The switch has an internal retainer within the switch housing and engageable by the cylinder housing in the first compression stroke of the cylinder, to shift the retainer and two electrical contacts thereon to a set position exactly suiting the cumulative buildout tolerance of the vehicle or other machine on which the novel combination is mounted. The retainer is locked there against reverse movement when the cylinder again extends and thereby withdraws from the switch. Another electrical contact is located on a switch plunger that moves axially back and forth with the retainer and switch housing. Thus, each repeat extension by the cylinder causes interengagement of the three electrical contacts.
