    Do you really need that exact switch? Being panel mount, there should be a few dozen to choose from that perform the function and fit in the available space, and of course, meet the required electrical spec volts and amps.

    Sir Stephen Hall . . . . .

    DON"T GUESS ! . . .let me tell you . . . its being a Push-on Push- off switch from a PFAFF models
    1221, 1222, 1222E & 1222SE #70-112000-02. sewing machines work light.

    With repeated use, its mechanical latching works may have failed within the switch housing . . . . . OR . . . . . bad contact action may have developed with its contacts.

    If being contacts, one might swing out the 4 tabs at the bottom of the switch to let the switch be slid apart, where you then s . .l. .o . .w . .l . .y and methodically observe and disassemble the unit to clean the contact areas and brush clean with denatured alcohol. Then with it being all nice and clean inside and having polished metal contacts. . . trial test it.

    If all is well, then slide the side support rails apart and compress inwards slightly to be able to get a tight clamping to the case when you reassemble again.
    BUT . . . for contact longevity and anti oxidance, get a small tin of silicone grease from a plumbers supply . . . its product identified as being " Plumbers Silicone Grease". Toothpick / apply it on the switches, just cleaned metal contact areas.
    Then you slide back together and re crimp the 4 end tabs.

    For . . A . . .price, the Exact unit is available as :

    OR . . .since it is MERELY switching a small wattage lamp . . . and IF you only see 2 connecting wires . . . any SPST toggle switch or latching PUSH switch, being of your AC line voltage rating and " fitting the hole " should substitute for reliable use for another 52 years.

    Furthermore . . . since the contacts / connecting wires did not show in your photos profile as was being shown . . . . do a double check against our most honorable . . . FUZZ meisters . . . . info on . . .Post #3 . . .for connections.
    BUT, your switch minimally qualifies as requiring a Single Pole Single Throw switching action and is definitely being a latching type of switch, or the light would go off, just as soon as you let off pressure on the switch pushbutton.
