You can google Contura switches or Carling rocker switches. You can buy just the rocker cap or the full unit. Be aware there are a zillion configurations for the switch bodies … DPDT (double pole double throw), SPDT, SPST, lamp configuration, momentary, etc so check carefully there should be a 4 digit code on the switch body like V1D1.
Check out the datasheet link on this page;
