Selco manufactures disc temperature switches (thermostats). There are five models of 1/2" automatic reset disc switches, and two models of 1/2" manual reset disc switches to choose from. Selco also offers 3/4" disc temperature switches in either automatic or manual reset configurations. Their 1/2" hermetically sealed thermostats offer a temperature range of -67ºF to 550ºF (-54ºC to 288ºC).

National Semiconductor manufactures temperature switches with factory preset or user programmable set points. Set point ranges vary from -55 to 150°C. The LM26LV is a low-voltage, precision, dual-output, low-power temperature switch.The LM26 is a single digital-output, low-power thermostat. The LM56 is a dual output low power thermostat.

Ashcroft manufactures the GT model temperature switches with a stainless steel enclosure for corrosion protection, LT temperature switches for general purpose industrial applications, the PT-N7 with a dual chamber design for added safety, and the T400 and T700 for most process applications.

Dwyer Instruments manufactures a variety of temperature switches, including thermocouple, digital, thermocouple limit control, dual stage, digital temperature/water level, and digital refrigeration temperature switches. Thermocouple types monitor and control temperature in heating and cooling applications. Digital switches offer tactile front keypads.

Kayden Instruments manufactures temperature switches for liquids, gases, are and slurry applications. Features include 4-20 mA current Loop for analog monitoring and universal power input (12-24 VDC and 115-230 VAC). Temperature switches come in threaded, retractable threaded, threaded single, threaded in-line, flanged, retractable flanged, flanged in-line, and sanitary flanged styles.

Nason manufactures four different models of temperature switches. Their TT model is a bi-metal immersion temperature switch with factory preset temperature and direct action contacts (minimum hysteresis). The TD model uses the snap disc approach to sense temperature and is factory preset. Their TM model utilizes a bellows mechanism to sense temperature. Their HT model uses a bellows high amp design.

CPI (Control Products, Inc.) manufactures two types of temperature switches. Their bimetalicc thermal switches offer a temperature range of 0 - 600°F and come in six different series'. Their rod and tube thermal switches have a temperature range of 0 - 1750°F and have five different series' to choose from.

Hydra Electric offers the 60H-T lightweight miniaturized temperature switch, designed for hydraulic, oil and fuel system temperature control. This unit's design utilizes a saturated vapor probe thermal system and a constant modulous negative rate disc spring sensing mechanism to provide quick responses and accurate settings. Welded hermetic stainless steel construction.

Barksdale manufactures bi-metal and snap disc temperature switches in many varieties, including explosion proof, industrial, general purpose and hazardous area types. Temperature ratings range from -50° to 600°F. The Series ML1S features a one-piece, brass thermowell design, which houses a bi-metallic, SPST snap switch.
