Control Circuit Limit Switch
Type VC40A
Publication Number: LS003/1211
Application
The rugged, low cost VC40A switch is used with a suitable operating ramp, to limit the travel of electric lifts and skiphoists
etc. requiring accurate positioning at low speeds. It is supplied with normally-closed contacts and an earth safety screen.
Operation
The switch is operated by the application of at least 0.9kg pressure against the roller, through a distance of approximately
25mm. Allowance is made for up to 22mm follow-through.
Installation
The switch case has integral brackets offering three-hole fixing either on the back face or the side opposite the arm. This
gives options in the direction of arm travel and thus of the plane in which the operating ramp can be mounted. The arm
has approximately 19mm of lateral adjustment on its shaft and is clamped at the desired angle, and may be mounted on
either side.
Construction
The switch is housed in an orange moulded glass-filled polycarbonate case. The transparent cover is in clear
polycarbonate, hinged at the bottom and opened by screwdriver pressure at the top. The lever arm is in passivated zinc
steel and the roller is a synthetic elastomer moulding.
Contacts
Silver plated hard-drawn copper with self cleaning wiping action. All terminals are push-on-type including the centre
earth shield.
Contact Rating
5A @240V a.c., 2A @240V d.c.
Weight
270g.
