Element KLT 1-6 Single Phase Power / Pressure Switch (ELT-5 Type)

This device is an industrial single-phase electric power / pressure switch control assembly branded under the Element line (Model: KLT 1-6).

This component functions as an electro-mechanical safety and automation control interface. It is engineered to automatically open or close an electrical circuit based on system demand or underlying fluid/air pressure changes. It is commonly integrated into single-phase water pump systems, small industrial air compressors, and heating/ventilation equipment.

Key Features

Heavy-Duty Double-Pole Contact Block: Built with two independent, robust terminal track levels equipped with heavy-duty brass fastening screws. This dual-contact terminal structure ensures clean wire distribution and secure, low-resistance electrical connections.
Rugged Steel Base Construction: Mounted on a thick, zinc-plated passivated steel base plate. This framework resists mechanical distortion, alignment shifts, and corrosive degradation in high-humidity pump rooms or industrial environments.
Integrated Cable Relief Bushings: Equipped with dual heavy-duty black rubber grommets/bushings on the front mounting flange. These guide the incoming power supply and motor lines into the terminal housing while protecting the wire sheaths from sharp metal edge wear and vibration strains.
Mechanical Trip Mechanism: Utilizes an internal snap-action spring configuration connected to a reinforced polymer top plunger. This design forces the electrical contacts open or closed instantly, preventing contact arcing and extending the overall operating life of the switch.

Applications

Single-Phase Water Booster Pumps: Acts as the primary control interface for residential and commercial well pumps or booster sets, turning the pump motor on or off based on system line pressure thresholds.
Small-Scale Air Compressors: Regulates pressure limits on small garage or workshop air compressors by cutting power to the drive motor when the storage tank reaches its maximum safe storage rating.
HVAC and Boiler Safety Loops: Integrated into industrial heating networks and ventilation manifolds as a high-limit safety cut-off switch to disrupt power if fluid or air pressure values exceed factory limits.
Agricultural Irrigational Feeds: Controls small distribution pumps and chemical dosing feeders across agricultural nurseries and localized greenhouse drip grids.
