End Reed switch failures and simplify switching larger AC reactive loads with our new 5 Amp AC Switch Sets.

One of the most common causes of failures in magnetic reed switch flow switches and level switches is welded shut contacts caused by switching reactive electrical loads such as electromechanical relays, solenoid valves, motor starters, motors, pumps, and incandescent loads. Even if the load does not exceed the reed switches rating, reactive loads cause arcing across the reed switch contacts and cause reed switch contacts to weld/stick shut. Contact protection must be added to your circuit to ensure reliability.

Eliminate costly and hazardous failures in the field. Our ERECTA SWITCH 5 AMP AC switch sets turn fragile reed switches into 5 amp AC powerhouses. These switch sets make it possible to switch 5 Amp reactive loads at 120VAC-240VAC with 25 amp inrush, isolating the reed switch from the load.

The 5-21 Straight Body Flow Switch is the best bargain in OEM low flow sensor applications. The no nonsense 5-21 flow switches are available in 5 factory flow switch set points .1 gpm, .25 gpm, .5 gpm, .75 gpm, and 1 gpm. Mount vertically without the titanium spring and sense even lower flow sensor rates. Built in 9/16 UNF female bosses are intended to be used with one of our 4 available flow switch accessory fittings. (Fitting serves as stop for flow switch poppet and spring in out flow port)

50-NP-AC5 Description

50-NP-AC5 Solid State NistorPac is a packaged Teccor alternistor that boosts switching capability of reed switch devices to 5 amps AC. If you are looking for a simple, compact, affordable way to protect reed switch devices or other pilot load switching devices from large loads this is it. NistorPacs can switch solenoid valves, small pumps, motor starters, alarms or any other AC loads up to 5 amps. If you already have integrated circuitry and need to add a high level or low level cut off or alarm, the NistorPac is an excellent solution.

The NistorPac has no shared terminals, a built-in heat sink, and built in hold downs making it a quick, simple, convenient, low cost control solution. Teccor’s alternistor is specifically designed for applications that switch highly inductive loads. A special chip offers the same performance as two thyristors (SCRs) wired inverse parallel (back-to-back), providing better turn-off behavior than a standard triac. This new chip construction provides two electrically separate SCR structures, providing enhanced dv/dt characteristics while retaining the advantages of a single-chip device. The NistorPac works in 24 – 240 Volts AC.
