A mechanical apparatus for flashing a hookswitch of a telephone set. The apparatus is comprised of a baseplate for retention on a telephone set, and first and second co-operative planar members resiliently hinged to an edge of the baseplate, whereby the second member depresses the hookswitch in response to the first member being depressed a first predetermined amount, and subsequently releases the hookswitch in response to the first member being further depressed. The apparatus provides an accurately timed hookswitch flash in response to simple mechanical co-operation between the first and second members. The apparatus is easily installed, does not require specially modified circuitry and is highly reliable as a result of its simple construction.
