750 Series
Pneumatic timers
Miniature momentary time-delay switches for OEM applications. Press the button and the contacts stay actuated for the time you set, controlled by air, with no power needed.
A brass knob on the back meters an internal flow of air to set the delay. Close tolerances, hand-built assembly and all-metal construction give precise, repeatable timing and long life. They're inside our own time-delay pushplates and in switch assemblies across the security and industrial controls industry.
