Safety interlock switches from Banner Engineering include SI-MAG Series 3-component magnet style switches that tolerate dirt buildup, washdowns, and misalignment; locking style switches with several choices of locking mechanisms and operating voltages; and compact plastic style safety interlock switches available in both limit switch and flat-pack styles.

Euchner-USA offers safety switches in both design type 1 with integrated actuator, and type 2, with separate actuator. Type 1 safety switch options include the NM Series, which is plastic with two narrow body designs, up to three contacts, and six different actuator heads. Type 2 safety switches are differentiated by those with locking and those without.

Leuze Electronic manufactures four series of safety switches. The S20 safety switch comes without guard interlocking, and is made of fiberglass-reinforced plastic in accordance with IP67. As with all the company's safety switches, its contact sets are suited for integration up to category 4, according to EN ISO 13849.

SICK manufactures both electro-mechanical and non-contact safety switches. The electro-mechanical types come in four groupings: separate actuators, locking devices, position switches, and safety hinge switches. Up to four total positive opening contacts are available on the switches, which are made of either plastic or metal.

Allen-Bradley offers interlock, trapped key, and safety limit safety switches. The interlock switches come in tongue interlock, guard locking, non-contact, and hinge configurations, and offer different options on how the switch can be operated and mounted on the guard. Safety limit switches are available in two styles: IEC or NEMA.

Power Components offers interlock and rope pull safety switches from Banner Engineering. The interlock switches include SI-MAG Series 3-component magnet style switches that tolerate dirt buildup, washdowns, and misalignment, locking style switches with several choices of locking mechanisms and operating voltages, and compact plastic style safety interlock switches available in both limit switch and flat-pack styles, with a choice of actuators.  Rope pull switches are available in spans ranging from 6 to 100 m, with trip and latch switch models available; minimum switch life is 1 million.

IDEM specializes in safety interlock switches, including tongue, solenoid locking, rope, non-contact, and explosion-proof ATEX switches. Mechanical interlock switches include Kobra tongue switches in three types: KM provides 3 or 4 pole contact blocks and die cast metal housing; KP offers 3 features entries and polyester body, as well as explosion-proof contact block versions; and IDIS-1 is a compact version with positive opening safety contacts to IEC 947-5-1. Additionally, the hinged IDIS-2 provides 180-degree contact operation at 5 degrees, a rugged plastic body, and metal enclosure protected to IP66/67. For most models, conduit entries are fitted to M20 or 0.5".
