Application Information and Terms

Snap Action Switches
T-Direct uses only the highest quality snap action electrical switches which insures a positive, instantaneous electrical contact under all operating conditions.

Diaphragms
T-Direct pressure switches incorporate elastomeric diaphragms to provide a positive media seal. Nitrile is the material of choice for most applications. Ethylene propylene, fluorocarbon, fluorosilicon, and neoprene are readily available for specific applications.

Differential
A distinct change in pressure (or temperature for temperature switches) is necessary to reset a T-Direct snap action switch to its original electrical state. This feature prevents “chatter” and maximizes switch and system life. Catalog ranges are typical mid range and can be varied with special construction.

Electrical Connections
A wide variety of electrical connectors are readily available for most applications. Screw terminals, wire leads, blades, studs, conduit, automotive DIN and military connectors are available.

Media Connections
T-Direct’s offering of media connections is unmatched in the industry. NPT, BSP, SAE, JIS, DIN, MS and many others are readily available.

Electrical Circuits
A unique variety of electrical contact arrangements allows the system designer to achieve complex logic at minimal cost. Isolated dual set points are available.

Electrical Rating
Most T-Direct switches are available in a nominal 5 or 10 AMP rating. Gold plated contacts for low current and 25 AMP ratings are also available on limited models.

Life
The operational life of a T-Direct switch is normally in excess of one million cycles. Operating life depends on many variables, and specific tests should be run if marginal conditions exist.

Application
T-Direct switches are used successfully in a great variety of pneumatic and hydraulic applications. Military vehicles and equipment, aviation, marine, machine tools, farm and construction equipment, process equipment, medical equipment and industrial machinery are typical applications.

Customization
T-Direct has the experience and willingness to customize any switch to meet specific application requirements. Special media connections, electrical connections, circuitry and construction materials can be designed and produced as needed.
