The use of the button-operated latch, besides facilitating a quick, one-handed flash attachment and detachment, also eliminates the possibility of the flash gradually working itself loose and shifting in the shoe, which on camera systems using the ISO 518 hot-shoe can lead to certain contacts being broken, contacts with the wrong pins being ...
The length of the sleeves prevents any live contacts from being exposed while the plug is being inserted or removed. An early method of sleeving the pins involving spring-loaded sleeves is described in the 1967 British Patent GB1067870. [47] The method actually adopted is described in the 1972 British Patent GB1292991. [48]
Both adapters route through the "F2" and "F3" signals; the Auto-lock hotshoe's "F1" signal is connected to the middle contact of the Multi Interface shoe, not pin 20 ("F1#"), which is left open. MIS pins 7 and 15 ("REG_GND") are internally connected to both sides of the frame as well as to the GND signal of the Auto-lock shoe's side.
2. All pins are equally likely to fail in the same way. 3. A pin, if inadvertently bent, is equally likely to bend in any direction. 4. A bent pin that has been pushed flat against the mating surface of its insert may be slightly curved. 5. An unwired bent pin that can touch two or more electrical paths simultaneously has open and shorted ...

Pin compatibility is a property desired by systems integrators as it allows a product to be updated without redesigning printed circuit boards, which can reduce costs and decrease time to market. Although devices which are pin-compatible share a common footprint, they are not necessarily electrically or thermally compatible.
