Jayashree Electron offers electronic speed switches and electrodynamic speed switches. Electronic speed switches come in many models, including heavy duty, light duty, indoor, hybrid ciruitry, digital IC technology, discreet IC technology, micro-controller technology, weatherproof, and compact configurations. Electrodynamic speed switches feature speed dependent contact actuation by eddy current torque that results in instant response even to small speed changes, and actuation speeds from 30-3000 RPM in 6 ranges.

Protocontrol is a manufacturer and exporter of safety switches for material handling plants. They offer zero speed switches (conveyor safety switches) and inductive proximity switches (industrial sensors for sensing position and speed).

Control Concepts manufactures electro mechanical, electronic, and proximity speed switches. Electro mechanical speed switches open or close contacts mechanically. Electronic speed switches open or close a set of contacts through a relay and an electronic circuit. A proximity speed switch is a non-contacting speed switch relying on a proximity sensor to pickup a rotating piece of ferrous metal.

Torq Corporation manufactures electronic speed switches, zero speed switches, and mechanical speed switches. Electronic and zero speed switches come in either standard or hazardous location models. The Torq mechanical speed switch is used in bulk material handling/processing systems to monitor speeds of conveyors, elevators, feeder shafts and drums.
