Abstract: A programmable solid-state relay includes a base module; a configuration module; a control voltage module having an energy storage device; a controller module having at least two microcontrollers, each having an internal EEPROM memory and at least one digital timer; and at least one switch module including at least one switching circuit having first and second switching contacts. The control voltage module is adapted to receive an applied control voltage and to permit pre-selection of an activation voltage level and a de-activation voltage level.

Abstract: A locking arrangement comprising: a handle assembly; a primary locking mechanism comprising a locking bar having a first shoulder and a second shoulder, which bar is movable between an extended locking position and a retracted release position, whereby when the locking bar is in the retracted release position, the handle assembly is movable “between a latched condition and an unlatched condition; a secondary locking mechanism having an override means, wherein when the override means is independently urged against the first and/or second shoulder of the locking bar, the locking bar is reversibly movable between the extended locking position and the retracted release position; and a biased catch means to releasably retain the locking bar in either the extended locking position or the retracted release position.
