Accessories for Tongue and Guard Locking Switches

The correct actuator for your application

A large variety of tongue actuators are available:

Standard: 90º, Flat, Standard

Flexible: Semi and Fully

Specialty: Extended Flat and GD2 models

				Standard type actuators accommodate most of the applications. Their design allows for the actuator and the switch to be mounted in different position and the guard to work properly. The flat actuator is mounted on small rubber blocks allowing for some play when the guard closes. The 90º is typically used on sliding doors.
				Flexible type actuators are used when doors are sagging or are not sturdy enough to guarantee insertion of the actuator always in-line with the opening of the switch. The flexible actuator allows for some motion of the actuator to "self” align with the opening of the switch. Fully flexible actuators allow the actuator to move within a 15º angle in any direction. Semi-flexible actuators can be used for tight angles where the actuator enters the switch at an angle. This angle is adjustable on the actuator. The semi-flexible actuator moves only in a single plan direction.
				GD2 actuators are dedicated actuators for GD2 models and are not suitable for use with standard models.
				Extended flat type actuator is used mostly when the actuator is mounted on a chain and inserted in the switch. The guard is latched and the key is just inserted in the switch attached to a chain. When the door opens, the chain pulls the actuator activating the safety contacts.
