Designed to replace the traditional ?missile? style or toggle switches, the digitally operated keypad lock/unlock system eliminates the possibility of knocking a release switch accidentally.
?The unique keypad has a four digit code locking system which prevents this accidental activation,? managing director Jeremy Doherty explained. ?We?ve also incorporated the ability to have unique codes for each operator for added security. Once in use, the keypad runs a self-check on start-up, and a warning buzzer and flashing light activates, when in unlock mode.?
The Snaplock+ Coupler features a Dual Pin Locking (DPL) system to ensure attachments remain securely engaged on both pins, in the event of loss of engagement force.
