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.

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.

Honeywell Sensing & Control offers Micro Switch safety switches in every size for both end users and OEM. Options include miniature switches (<50 mm) for smaller doors and openings, trapped key and solenoid key switches for large, heavy doors, cable pull switches for conveyor or perimeter guarding, and non-contacting switches for small door position detection. These switches, made from everything from plastic to die-cast zinc, provided mechanical life from 1 million up to 15 million, cable length as long as 10 m (prewired), and ampere rating ranges from 1 to 100 mA low energy, to 50 mA to 10 A thermal.

Omron carries an array of safety switches designed to work together with hinged, sliding, or lift-off guards and barriers; when the guard is opened, the power supply to the machine is disconnected.  They offer both compact and non-compact rope pull safety interlock switches for mounting widths as small as 40 mm, rated to IP67 (NEMA6), and rope spans up to 200 m. Guard door locking safety switches are also available.

Schneider Electric provides safety switches for light to heavy duty, as well as a variety of specialized models. General duty safety switches for residential and commercial applications (e.g. lighting, air conditioning, appliances) are available fusible and non-fusible, and 30-800 A rated for application loads up to 240 V. Light duty safety switches are available in three single-phase styles with a 30 A maximum rating, while heavy duty switches cover a range from 30-1,200 A with a 240 or 600 Vac maximum.

Schmersal offers a full line of point of operation machine guarding products, such as keyed interlock switches, hinged interlock switches, and safety-rated limit switches. Safety-rated limit switches include the Z/T235, which is available with a choice of six standard actuators that are mountable in any of four 90-degree positions, and the Z332, which is housed in rugged metal and IP65 rated.

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.

Pilz offers five lines of safety switches for gate and position monitoring. PSENmech mechanical safety switches use increased extraction force on actuators to ensure that gates cannot be opened unintentionally, while PSENmag switches use non-contact, magnetic technology to monitor the position of movable guards and other objects.

EE Controls specializes in safety interlock switches, rope pull switches, and other machine safety switches to protect personnel from hazardous machinery. Interlock switches are available with NEMA 4- or 12-rated thermoplastic bodies with door-holding force ratings of 2, 7, or 22 lbs., or with metal bodies with up to 23 lbs. of holding force.

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.
