"EUCHNER SGA Safety Switches are used to protect personnel by monitoring and interrupting the safety circuit depending on the position of the machine guard. To meet current worldwide standards, safety interlock components cannot be easily bypassed. These switches have positive opening contacts and redundancy to guarantee that they fail to a safe state. The SGA safety switches have a metal housing which is identical to the GP and SGP safety switches. A SGA extended version is also available, which has the ability for up to two pushbuttons."
